 1.63  29-Jan-2020  thorpej Adopt <net/if_stats.h>.
 1.62  05-Feb-2019  msaitoh branches: 1.62.6;
Remove very old IFF_NOTRAILERS flag.
 1.61  03-Sep-2018  riastradh Rename min/max -> uimin/uimax for better honesty.

These functions are defined on unsigned int. The generic name
min/max should not silently truncate to 32 bits on 64-bit systems.
This is purely a name change -- no functional change intended.

HOWEVER! Some subsystems have

#define min(a, b) ((a) < (b) ? (a) : (b))
#define max(a, b) ((a) > (b) ? (a) : (b))

even though our standard name for that is MIN/MAX. Although these
may invite multiple evaluation bugs, these do _not_ cause integer
truncation.

To avoid `fixing' these cases, I first changed the name in libkern,
and then compile-tested every file where min/max occurred in order to
confirm that it failed -- and thus confirm that nothing shadowed
min/max -- before changing it.

I have left a handful of bootloaders that are too annoying to
compile-test, and some dead code:

cobalt ews4800mips hp300 hppa ia64 luna68k vax
acorn32/if_ie.c (not included in any kernels)
macppc/if_gm.c (superseded by gem(4))

It should be easy to fix the fallout once identified -- this way of
doing things fails safe, and the goal here, after all, is to _avoid_
silent integer truncations, not introduce them.

Maybe one day we can reintroduce min/max as type-generic things that
never silently truncate. But we should avoid doing that for a while,
so that existing code has a chance to be detected by the compiler for
conversion to uimin/uimax without changing the semantics until we can
properly audit it all. (Who knows, maybe in some cases integer
truncation is actually intended!)
 1.60  15-Jul-2018  maxv Retire ipkdb entirely. The option was removed from the config files
yesterday.

ok kamil christos
 1.59  26-Jun-2018  msaitoh branches: 1.59.2;
Implement the BPF direction filter (BIOC[GS]DIRECTION). It provides backward
compatibility with BIOC[GS]SEESENT ioctl. The userland interface is the same
as FreeBSD.

This change also fixes a bug that the direction is misunderstand on some
environment by passing the direction to bpf_mtap*() instead of checking
m->m_pkthdr.rcvif.
 1.58  22-Jun-2018  msaitoh It's not required to include net/bpfdesc.h. Remove it.
 1.57  15-Dec-2016  ozaki-r branches: 1.57.8; 1.57.14;
Move bpf_mtap and if_ipackets++ on Rx of each driver to percpuq if_input

The benefits of the change are:
- We can reduce codes
- We can provide the same behavior between drivers
- Where/When if_ipackets is counted up
- Note that some drivers still update packet statistics in their own
way (periodical update)
- Moved bpf_mtap run in softint
- This makes it easy to MP-ify bpf

Proposed on tech-kern and tech-net
 1.56  02-Oct-2016  christos MFREE -> m_free
 1.55  10-Jun-2016  ozaki-r branches: 1.55.2;
Introduce m_set_rcvif and m_reset_rcvif

The API is used to set (or reset) a received interface of a mbuf.
They are counterpart of m_get_rcvif, which will come in another
commit, hide internal of rcvif operation, and reduce the diff of
the upcoming change.

No functional change.
 1.54  09-Feb-2016  ozaki-r Introduce softint-based if_input

This change intends to run the whole network stack in softint context
(or normal LWP), not hardware interrupt context. Note that the work is
still incomplete by this change; to that end, we also have to softint-ify
if_link_state_change (and bpf) which can still run in hardware interrupt.

This change softint-ifies at ifp->if_input that is called from
each device driver (and ieee80211_input) to ensure Layer 2 runs
in softint (e.g., ether_input and bridge_input). To this end,
we provide a framework (called percpuq) that utlizes softint(9)
and percpu ifqueues. With this patch, rxintr of most drivers just
queues received packets and schedules a softint, and the softint
dequeues packets and does rest packet processing.

To minimize changes to each driver, percpuq is allocated in struct
ifnet for now and that is initialized by default (in if_attach).
We probably have to move percpuq to softc of each driver, but it's
future work. At this point, only wm(4) has percpuq in its softc
as a reference implementation.

Additional information including performance numbers can be found
in the thread at tech-kern@ and tech-net@:

Acknowledgment: riastradh@ greatly helped this work.
Thank you very much!
 1.53  27-Oct-2012  chs branches: 1.53.14;
split device_t/softc for all remaining drivers.
replace "struct device *" with "device_t".
use device_xname(), device_unit(), etc.
 1.52  26-Jul-2011  mrg branches: 1.52.2; 1.52.12;
convert to device_t, cfdata_t and CFATTACH_DECL_NEW.
 1.51  08-Aug-2010  chs remove an unused variable.
 1.50  05-Apr-2010  joerg Push the bpf_ops usage back into bpf.h. Push the common ifp->if_bpf
check into the inline functions as well the fourth argument for
bpf_attach.
 1.49  19-Jan-2010  pooka branches: 1.49.2; 1.49.4;
Redefine bpf linkage through an always present op vector, i.e.
#if NBPFILTER is no longer required in the client. This change
doesn't yet add support for loading bpf as a module, since drivers
can register before bpf is attached. However, callers of bpf can
now be modularized.

Dynamically loadable bpf could probably be done fairly easily with
coordination from the stub driver and the real driver by registering
attachments in the stub before the real driver is loaded and doing
a handoff. ... and I'm not going to ponder the depths of unload
here.

Tested with i386/MONOLITHIC, modified MONOLITHIC without bpf and rump.
 1.48  12-May-2009  cegger struct device * -> device_t, no functional changes intended.
 1.47  12-May-2009  cegger struct cfdata * -> cfdata_t, no functional changes intended.
 1.46  18-Apr-2009  tsutsui Remove extra whitespace added by a stupid tool.
XXX: more in src/sys/arch
 1.45  20-Mar-2009  cegger Correct bungled bcopy() -> memcpy() conversion
 1.44  18-Mar-2009  cegger bcopy -> memcpy
 1.43  14-Mar-2009  dsl Change about 4500 of the K&R function definitions to ANSI ones.
There are still about 1600 left, but they have ',' or /* ... */
in the actual variable definitions - which my awk script doesn't handle.
There are also many that need () -> (void).
(The script does handle misordered arguments.)

*** Summary ***

When a link-layer address changes (e.g., ifconfig ex0 link
02:de:ad:be:ef:02 active), send a gratuitous ARP and/or a Neighbor
Advertisement to update the network-/link-layer address bindings
on our LAN peers.

Refuse a change of ethernet address to the address 00:00:00:00:00:00
or to any multicast/broadcast address. (Thanks matt@.)

Reorder ifnet ioctl operations so that driver ioctls may inherit
the functions of their "class"---ether_ioctl(), fddi_ioctl(), et
cetera---and the class ioctls may inherit from the generic ioctl,
ifioctl_common(), but both driver- and class-ioctls may override
the generic behavior. Make network drivers share more code.

Distinguish a "factory" link-layer address from others for the
purposes of both protecting that address from deletion and computing
EUI64.

Return consistent, appropriate error codes from network drivers.

Improve readability. KNF.

*** Details ***

In if_attach(), always initialize the interface ioctl routine,
ifnet->if_ioctl, if the driver has not already initialized it.
Delete if_ioctl == NULL tests everywhere else, because it cannot
happen.

In the ioctl routines of network interfaces, inherit common ioctl
behaviors by calling either ifioctl_common() or whichever ioctl
routine is appropriate for the class of interface---e.g., ether_ioctl()
for ethernets.

Stop (ab)using SIOCSIFADDR and start to use SIOCINITIFADDR. In
the user->kernel interface, SIOCSIFADDR's argument was an ifreq,
but on the protocol->ifnet interface, SIOCSIFADDR's argument was
an ifaddr. That was confusing, and it would work against me as I
make it possible for a network interface to overload most ioctls.
On the protocol->ifnet interface, replace SIOCSIFADDR with
SIOCINITIFADDR. In ifioctl(), return EPERM if userland tries to
invoke SIOCINITIFADDR.

In ifioctl(), give the interface the first shot at handling most
interface ioctls, and give the protocol the second shot, instead
of the other way around. Finally, let compatibility code (COMPAT_OSOCK)
take a shot.

Pull device initialization out of switch statements under
SIOCINITIFADDR. For example, pull ..._init() out of any switch
statement that looks like this:

switch (...->sa_family) {
case ...:
..._init();
...
break;
...
default:
..._init();
...
break;
}

Rewrite many if-else clauses that handle all permutations of IFF_UP
and IFF_RUNNING to use a switch statement,

switch (x & (IFF_UP|IFF_RUNNING)) {
case 0:
...
break;
case IFF_RUNNING:
...
break;
case IFF_UP:
...
break;
case IFF_UP|IFF_RUNNING:
...
break;
}

unifdef lots of code containing #ifdef FreeBSD, #ifdef NetBSD, and
#ifdef SIOCSIFMTU, especially in fwip(4) and in ndis(4).

In ipw(4), remove an if_set_sadl() call that is out of place.

In nfe(4), reuse the jumbo MTU logic in ether_ioctl().

Let ethernets register a callback for setting h/w state such as
promiscuous mode and the multicast filter in accord with a change
in the if_flags: ether_set_ifflags_cb() registers a callback that
returns ENETRESET if the caller should reset the ethernet by calling
if_init(), 0 on success, != 0 on failure. Pull common code from
ex(4), gem(4), nfe(4), sip(4), tlp(4), vge(4) into ether_ioctl(),
and register if_flags callbacks for those drivers.

Return ENOTTY instead of EINVAL for inappropriate ioctls. In
zyd(4), use ENXIO instead of ENOTTY to indicate that the device is
not any longer attached.

Add to if_set_sadl() a boolean 'factory' argument that indicates
whether a link-layer address was assigned by the factory or some
other source. In a comment, recommend using the factory address
for generating an EUI64, and update in6_get_hw_ifid() to prefer a
factory address to any other link-layer address.

Add a routing message, RTM_LLINFO_UPD, that tells protocols to
update the binding of network-layer addresses to link-layer addresses.
Implement this message in IPv4 and IPv6 by sending a gratuitous
ARP or a neighbor advertisement, respectively. Generate RTM_LLINFO_UPD
messages on a change of an interface's link-layer address.

In ether_ioctl(), do not let SIOCALIFADDR set a link-layer address
that is broadcast/multicast or equal to 00:00:00:00:00:00.

Make ether_ioctl() call ifioctl_common() to handle ioctls that it
does not understand.

In gif(4), initialize if_softc and use it, instead of assuming that
the gif_softc and ifp overlap.

Let ifioctl_common() handle SIOCGIFADDR.

Sprinkle rtcache_invariants(), which checks on DIAGNOSTIC kernels
that certain invariants on a struct route are satisfied.

In agr(4), rewrite agr_ioctl_filter() to be a bit more explicit
about the ioctls that we do not allow on an agr(4) member interface.

bzero -> memset. Delete unnecessary casts to void *. Use
sockaddr_in_init() and sockaddr_in6_init(). Compare pointers with
NULL instead of "testing truth". Replace some instances of (type
*)0 with NULL. Change some K&R prototypes to ANSI C, and join
lines.

Zero out the buffer when padding packet to ETHER_MIN_LEN-ETHER_CRC_LEN
 1.30  22-Oct-2002  chs in ofnet_read(), interpret returns of either -2 or 0 from OF_read() as
meaning that there is no packet available. the OF spec reportedly
says that it's supposed to return 0 in this case, but my Firepower box
uses -2, so this is probably another of those FIRMWORKSBUGS things.
we'll accept both values in any case.
 1.29  02-Oct-2002  thorpej Add trailing ; to CFATTACH_DECL.
 1.28  02-Oct-2002  thorpej Use CFATTACH_DECL().
 1.27  30-Sep-2002  thorpej Use CFATTACH_DECL().
 1.26  27-Sep-2002  thorpej Declare all cfattach structures const.
 1.25  18-Sep-2002  chs use splnet() around the body of ofnet_read(). this is logically the
receive interrupt handler since it passes received packets to the
interface's input handler. that ends up scheduling a network softint
and queuing the packet on the interface's receive queue (in that order),
so if softnet isn't blocked at this point then softnet() doesn't find
the packet until it's triggered again by something else.
remove all vesitages of dk_establish().
 1.24  05-Mar-2002  itojun branches: 1.24.8;
bring in latest ALTQ from kjc. ALTQify some of the drivers.
 1.23  13-Nov-2001  lukem add RCSIDs
 1.22  20-Oct-2001  billc FCS check and padding for minimum size Ethernet packet
 1.21  26-Aug-2001  matt Make compile with -Wmissing-prototype -Wstrict-prototypes
 1.20  15-Nov-2000  thorpej branches: 1.20.2; 1.20.4;
Move bpfattach()/bpfdetach() calls into ether_ifattach()/ether_ifdetach().
 1.19  16-May-2000  thorpej Nuke dk_establish() from orbit except from those ports which still use
it to determine the boot device: mvme68k, pc532, macppc, ofppc. Those
platforms should be changed to use device_register(). In the mean time,
those ports defined __BROKEN_DK_ESTABLISH.
 1.18  23-Mar-2000  thorpej New callout mechanism with two major improvements over the old
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
resource allocation.
- Insertion and removal of callouts is constant time, important as
this facility is used quite a lot in the kernel.

The old timeout()/untimeout() API has been removed from the kernel.
 1.17  18-May-1999  thorpej branches: 1.17.2;
Rework layer 2 protocol input routines. Instead of calling e.g. ether_input()
directly, call the function pointer (*if_input)(ifp, m). The input routine
expects the packet header to be at the head of the packet, and will adjust
as necessary. Privatize the layer 2 input and output routines, allowing
*_ifattach() to set them up as appropriate.
 1.16  04-May-1999  thorpej Make this compile again.
 1.15  05-Jul-1998  jonathan branches: 1.15.6; 1.15.10;
defopt INET, NETATALK.
 1.14  10-Jun-1998  tv Missing include <sys/systm.h>.
 1.13  24-Feb-1998  mycroft Several things:
Clean up the name space here a bit.
Add a `busname' element to struct ofprobe (now struct ofbus_attach_args), and
check against it.
Nuke `ofroot'.
Rename the `openfirm' attribute to `ofbus'.
 1.12  27-Jan-1998  cgd Make sure the data after the Ethernet header is aligned. (It's been
in the Shark source tree for a while, but Jason's recent commit to
dp8390.c spurred me to check it in here.)
XXX Assumes the device is an ethernet, but then so does other code in
this driver.
 1.11  22-Jan-1998  cgd fix typo: s/max-address/mac-address/
 1.10  12-Jan-1998  thorpej Update for config changes.
 1.9  28-Apr-1997  mycroft Oops; forgot to GC the last mbuf allocated when out of clusters.
Also, DTRT if OF_read() returns 0 when no data is available..
 1.8  24-Apr-1997  mycroft Fix typo in previous.
 1.7  24-Apr-1997  mycroft If we fail to allocate a cluster to hold a large packet, simply
drop it rather than using a chain of tiny mbufs.
 1.6  16-Apr-1997  thorpej - Update for no __BROKEN_INDIRECT_CONFIG.
- Fix BPF hooks.
 1.5  15-Mar-1997  is New ARP system, supports IPv4 over any hardware link.

Some of the stuff (e.g., rarpd, bootpd, dhcpd etc., libsa) still will
only support Ethernet. Tcpdump itself should be ok, but libpcap needs
lot of work.

For the detailed change history, look at the commit log entries for
the is-newarp branch.
